One branch of linguistics that is the intersection of different disciplines is considered as Discourse analysis or Discourse studies. For centuries, interlinguistic relations have been the subject of research in such areas as rhetoric, public speaking, stylistics, and literature. In the twentieth century, the so-called discourse analysis was formed as an independent field of science in order to distinguish speech from language. Although not all disciplines fully recognize that discourse analysis operates as an independent branch of linguistics, whilst, it is very likely that it will happen in the near future. This article discusses the history, types, and differences between discourse and critical discourse analysis.
